Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 585

An engineer configured 802.1X authentication on a switch port but cannot authenticate. Which action must the engineer take to validate if the user credentials are correct?

Answer options

• A. Check the logs of the authentication server for the username and authentication rejection logs.
• B. Check policy enforcement point for the authentication mechanism and credentials used.
• C. Check the supplicant logs for the username and password entered, then check the authentication provider.
• D. Check the authenticator and view the debug logs for the username and password.

Correct answer: A

Explanation

The correct answer is A, as checking the logs of the authentication server will provide direct insight into whether the user credentials are being rejected and why. Options B and C focus on the enforcement point and supplicant logs, which may not directly confirm credential validity. Option D, while potentially useful, does not directly address the authentication logs, which hold the key information needed for this situation.
